/* INPUT FAILURE & FAIL STATE
An attempt to read invalid data, such as trying to put a letter into an int
or double, results in input failure. The input stream enters a state called
the "fail state." Once it enters fail state, all further I/O statements using
that stream are ignored. However, the program continues to execute with whatever
values are stored in variables and produces incorrect results.
